Abstract :
This paper presents the results of a propagation measurements campaign carried out using a 641 MHz signal transmitted over a typical suburban area of Rio de Janeiro city. With a mobile receptor, the variability characteristics of the received signal were analyzed on different routes and speeds of the measurement environment. Large and small scale fading of the received signal envelope were measured and compared with some known probability density functions in the UHF band. Statistics of the level crossing rate (LCR) were also measured in order to address the effect of mobile speed.
